Three outcomes, checked requirement by requirement
- Does not meet your requirements: at least one published fact establishes a violation, such as a motorhome longer than the equipment limit or a required outlet absent from an explicit outlet list.
- Needs verification: no confirmed violation, but at least one required condition is missing, conflicting, or cannot be interpreted safely.
- Meets the published limits: each chosen required condition has supporting evidence. This is a result for those selected checks, not a guarantee of physical access, suitability, or availability.
Unknown conditions outside your chosen requirements stay visible as cautions. The matching engine uses the same pure rules in the browser and automated tests.
Access comes first
The national directory includes overnight camping records for different kinds of trips. An explicit hike-in, walk-in or boat-in access rule does not meet a vehicle profile. Missing or conflicting access remains unverified. Equipment permission and length limits are checked separately; a tent, cabin or group-site listing never becomes an RV recommendation simply because it appears in the directory.
Length rules keep their meaning
Equipment-specific limits, generic maximum vehicle length, and driveway dimensions are separate facts. A driveway can be longer than the allowed RV. A generic length field with unknown measurement basis cannot produce a positive length result. Explicit minimum equipment lengths are checked as well: smaller equipment can be prohibited on a designated large-rig site. If source wording leaves equality at the minimum unclear, that boundary needs verification.
For trailers, the trailer-only length and the measured connected setup serve different rules. We never obtain connected length by adding the tow vehicle and trailer lengths. Detaching and parking a tow vehicle elsewhere is never assumed.
Feet, inches, and meters are converted before comparison. Equality is allowed by the numeric check and labeled At the published limit. We do not round an exceedance down, add an invented tolerance, or quietly apply a safety margin. Read the measurement guide.
Requirements and preferences do different jobs
Required hookups and accessibility features affect the result. Preferences only help order otherwise comparable results. Sorting uses requirement outcome first, then fewer unknown required conditions, then more matched preferences, then a stable site ID. There is no probabilistic or AI-generated suitability score.
An advertised 50A outlet does not confirm a 30A outlet. Campground drinking water does not establish a site water hookup. We never assume that an adapter, an extension, or an unmentioned parking arrangement resolves a requirement.
Accessibility is a set of features
An operator’s accessible designation is shown with attribution. It does not establish the path, slope, table design, toilet distance, or restroom features. Each has a separate fact and may be unknown. CampsiteCheck does not issue ADA or ABA certification, and no medical information is needed to use the tool.
Facts retain their origin
Source records are preserved as immutable snapshots with acquisition dates and SHA-256 hashes. Each normalized attribute retains its original value, source URL, scope, and source modification date when available. All source descriptions are treated as text.
A field is known, unknown, conflicting, or not applicable. An unresolved disagreement stays conflicting; the matcher treats it as unverified. A campground rule is inherited only when its wording establishes that it applies to the site. Evidence labels distinguish site and campground scope.
Our page quality policy
A site page is eligible for indexing only with valid identity, an official link, a linked snapshot reviewed within 90 days, and at least three useful fact groups. One group must establish an equipment or length rule with a known measurement basis. Its facts must differ meaningfully from another site in that campground. When multiple sites share an identical fact signature, only one stable representative is eligible for indexing; all actual records remain available in campground tables and the local comparison tool. Campground eligibility requires useful comparison of at least two real sites and documented limits.
These are CampsiteCheck editorial thresholds, not Google rules. Incomplete records stay in the directory and tool. We generate separate new site pages only for records that meet the editorial policy, while retaining previously published URLs with noindex when they do not qualify. All local and preview builds are noindex. No combination pages for state, rig length, amperage, or accessibility filters are created.
